i always wondered if some 'secret' weapon may have vaporized the plane and thats why the gov has been so sensitive about the attack on the pentagon. some say a missle hit the pentagon perhaps following the plane. evidence being the color of the explosion, the trailing smoke, and lack of debris. others say it was a global hawk, because of the way it manuevered and escaped radar, and the limited debris.
however if you want to look for something really interesting watch the 'collapse' of building 7 at the WTC site. WTC7 was never hit by a plane, yet imploded perfectly, you can see the penthouse fall in first and a crimp form on the building. All evidence points to the building being demolished, yet it was one hour after the other buildings were hit. You can google and find a video for that if you wish. perhaps the buildings come pre-wired and they dont want to scare people who work in them?

Please note im just reporting some "information" what-have-you that i have come across; not making any statements. considereding how this info was treated in the past on this forum, i would expect this thread to be locked/deleted and maybe some posts might get edited/deleted.
